Hello ESRI community,

I need help with a problem I am having using the ArcGIS API for JavaScript - v18. Well the problem is that I want to try to change the points that comes from a cycle-parking API by some images depending on the parking if it is "GOLD" or "SILVER" should place the image that corresponds to it with respect to the VALUE. Then as I am doing it it does not render me the points that I need to change by the images or it shows me the error, my code is the following one:

<html>
  <head>
    <meta charset="utf-8" />
    <meta
      name="viewport"
      content="initial-scale=1, maximum-scale=1, user-scalable=no"
    />
    <title>Prueba - ArcGIS API for JavaScript</title>
    <style>
      html,
      body,
      #viewDiv {
        padding: 0;
        margin: 0;
        height: 100%;
        width: 100%;
      }

      #titleDiv {
        position: absolute;
        height: 55px;
        width: 100%;
        display: flex;
        justify-content: space-between;
        color: #f8f8f8;
        background: #464646;
        z-index: 1;
      }

      #title {
        margin: 15px;
        font-size: 20px;
        overflow: hidden;
      }

      .invisible {
        visibility: collapse;
      }

      .esri-expand .esri-expand__content {
        box-shadow: none;
      }

      .esri-view-height-xsmall .esri-ui-corner .esri-expand .esri-legend.esri-widget,
      .esri-view-height-small .esri-ui-corner .esri-expand .esri-legend.esri-widget {
        max-height: 100%;
      }

      Haga clic en cualquier ubicación en el mapa para ver su dirección postal
    </div>
  </body>
</html>

The points I want to change for the images are these:

link api (https://services2.arcgis.com/NEwhEo9GGSHXcRXV/arcgis/rest/services/Cicloparqueaderos_Certificados_Bo...?)

Final or expected result, the problem with this api is that they are not all points (in short outdated) and also is another, but with the images have a result like the following image:

I hope you can help me, thank you.
